Abstract (en)

A replaceable inkjet printhead cleaner service station system (70) has separate replaceable cleaning units (80, 82, 84, 86) for each printhead (60, 62, 64, 66) in an inkjet printing mechanism (20), which has a pallet (72) that moves the cleaning units translationally to service the printheads. Each cleaning unit (80, 82, 84, 86) has a printhead wiper (125), a printhead snout wiper (190), a capping system (170), a spittoon (108), and optionally, an ink solvent application system (134). A service station pallet (72) moves a replaceable base (102) between rest and sealing positions, with the base defining a cam surface (110). A sled (150) has a cam follower (152) that rides along the cam surface (110), with the sled (150) supporting a cap lip (170). An activation wall (151) extends from the sled (150) to engage the printhead (60, 62, 64, 66) and move the sled (150) along the cam surface (110) to the sealing position through linear motion (76) of the pallet (72) while the printhead remains stationary. A method is provided for sealing an inkjet printhead (60, 62, 64, 66), along with a printing mechanism (20) employing such a capping system. <IMAGE>
